According to a railway board letter dated December 11, a copy of which is with news agency PTI, the board has formed a six-member committee to review the system and submit a report in 30 days.
The committee consists of railway board officials along with Ravinder Goyal, Adviser, NITI Ayog, Meenakshi Malik, Executive Director, Revenue Management, Air India, S Sriram, professor of transport economics and Iti Mani, Director, Revenue, Le Meridien, Delhi.
"The broad terms and reference of the committee shall be to examine all options and recommend the best option keeping in mind passengers and railways' interest", the letter stated.
The flexi-fare system, launched in September 2016, led to up to 50 per cent increase in fares. Under the formula, base fares increase from 10 per cent to 50 per cent with every 10 per cent of berths booked.
While revenue increased, the railways lost passengers as several berths remained vacant, officials said.
It has also suggested that the committee explore ways to offer adds-ons to passengers like loyalty benefits or deferred benefits for better patronage of the scheme.
The committee will also recommend if modifications or amendments can be brought to the the flexi-fare system to offer passengers flexibility of rates during peak season, lean season or during week days or weekends or during festivals.
The committee has also been asked to review the fares of the Humsafar Express which was launched last year.
